Upper fabric is holographic faux leather with acid green piping, platform spikes and accessories. Face accessories are removable. Synthetic rubber sole. New to HCD platforms? Choose the size nearest your most-often purchased AU size – for example if you are usually an AU9, sometimes 9.5, choose US9/AU9.5/VZ39. If you’re already a fan and are adding to your collection, HCD platforms run pretty true to the Chocs sizing you are used to, yay! Simply refer to the VZ size printed on the bottom of your shoe in a cute little love heart, and simply choose the same VZ size when ordering; for example if there’s a 37 in your love heart, then choose US7/AU7.5/VZ37. Easy peasy!
